Hello,
I'm new to matlab. Could any one help me how to create a bounding box with right angled triangle say the coordinates are (0, 0) (100, 0), (0, 150).
Thank you.

I assume that a bounding box is needed to be drawn over a right-angled triangle.
x1 = [0 1 0];
y1 = [0 0 1];
polyin = polyshape(x1,y1);
[xlim,ylim] = boundingbox(polyin);
plot(polyin)
hold on
rectangle('position',[xlim(1),ylim(1),xlim(2),ylim(2)])
The polyshape function create a 2-D polygon, here a right-angled triangle with the given vertices values.
The boundingbox function returns the x,y bounds of the smallest rectangle enclosing the triangle.
